Some sites cache results obtained from DNS beyond DNS TTL. I don't think
their DNS server caches the results (though I am willing to accept that
there are borked DNS implementations). It's more likely that whatever
$thing queries DNS is caching the result indefinitely or for too long.

and I am not talking about sites that interpret ~all as a -all.

and as a "client", I am not talking about recursive SPF records and
other funny stuff.
